How do you install the tube filter inlet?
Answer Hello Regina,
Turn the power and water supply off to the unit. Remove the water supply line from the end of the line. Reach under the unit to the filter housing and push the ring around the tube toward the filter housing while pulling the line out. To install the new one, push the line into the fitting until it bottoms then push harder. It will "pop" in another 1/4 inch approximately. To seat the fittings' seal, pull on the line without contacting the ring. Turn the water and power back on and throw away about 2 gallons of water to purge the system of any air. check the fitting for leaks.
